[0020] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", "front", "back", "inside", "outside", "vertical", "horizontal" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore are not to be construed as limiting the present invention. In addition, the terms "first", "second" and "third" are only used for descriptive purposes and are not to be construed as indicating or implying relative importance.

[0022] like Figure 1-3 It is a structural schematic diagram of a highly stable AC contactor terminal cover of a preferred embodiment of the utility model. In this embodiment, a highly stable AC contactor terminal cover comprises a contactor end cover 1 and a terminal cover 2 arranged at the front and rear ends of the contactor end cover 1. An installation cavity 3 is opened at the front and rear ends of the contactor end cover 1. A rotation opening 32 is opened at the rear end on both sides of the inner wall of the installation cavity 3, and a clamping block 31 is fixedly connected at the front end on both sides of the inner wall of the installation cavity 3. At the same time, a rotating rod 21 is fixedly connected at a relative position of the rotating opening 32 on both sides of the outer wall of the terminal cover 2, and the rotating rod 21 is rotatably connected in the rotating opening 32, so that the terminal cover 2 has a flipping function. At the same time, in order to make the terminal cover 2 have a fixing function, a bayonet 22 is provided on both sides of the outer wall of the terminal cover 2 at a position relative to the clamping block 31, and the clamping block 31 is clamped in the bayonet 22, so as to achieve the function of fixing the terminal cover 2 and the contactor cover 1; in specific use, when operating the wiring terminal, the terminal cover 2 is picked up by hand, the clamping block 31 leaves the bayonet, and the terminal cover 2 is turned upward with the rotating rod 21 as the center, so that the wiring terminal is completely exposed and can be directly operated; similarly, after the operation of the wiring terminal is completed, the terminal cover 2 is turned downward until the clamping block 31 is clamped in the bayonet 22, and the fixing function of the terminal cover 2 is achieved through the cooperation of the clamping block 31 and the bayonet. Combined with the above-mentioned structural design, the limiting effect of the terminal cover when operating the wiring terminal is effectively avoided, the service life of the terminal cover is improved, and the service life of the AC contactor is increased.

[0023] In this embodiment, a plurality of partitions 4 are fixedly installed in the installation cavity 3, and a wiring cavity 5 is formed between two partitions 4. A through hole 23 is provided at the top of the terminal cover 2 at a position relative to the wiring cavity 5, which is convenient for subsequent observation of whether the wiring terminal is loose. A wire threading hole 24 is provided at the front end face of the terminal cover 2 at a position relative to the wiring cavity 5, which is convenient for connecting the connecting wire to the wiring terminal.

[0024] In this embodiment, arc openings 41 are provided at the front ends of the tops of the plurality of partitions 4 and avoidance positions 33 are provided at the rear ends of the tops of the mounting cavities 3. This structural design prevents the terminal cover 2 from getting stuck during the flipping process, which may result in the terminal cover 3 being unable to flip.

[0025] In this embodiment, the terminal cover 2 and the rotating rod 21 are designed as an integrated structure, and the design increases the connectivity between the terminal cover 2 and the rotating rod 21, thereby increasing the service life of the flip.
